ABSTRACT:
A buckshot round for use in large, smooth-barreled weapons, such as an M203 or M79 grenade launcher, wherein the round itself acts as the firing barrel. In particular, a lethal buckshot round is provided, wherein an inner metal cylinder (barrel portion) is encased in an outer jacket, and a shot wad is contained in the inner metal cylinder, such that the inner metal cylinder acts as a barrel for firing of the buckshot from the smooth-barreled weapon. The barrel portion of the buckshot round acts as the firing barrel, and prevents contact of the buckshot with the weapon barrel during firing, thereby providing an accurate firing pattern and preventing damage to the weapon barrel.
